Description

Technical Field

[0001] The present invention relates to the technical field of renewable resource recycling and processing, in particular to a buckle removal device for a buckle-type strip packaging bag. Background Art

[0002] The snap-on strip packaging bags for industrial emulsion explosives are made of high-density polyethylene and polyester as the main raw materials, and the middle-wrapped composite film is made of polypropylene and polyethylene as the main raw materials. These composite films are all resin-based and can be used as combustible components of industrial explosives.

[0003] For empty bags and packaging bags of emulsion explosives removed during the industrial explosives production process, the buckles are primarily made of aluminum, which is of high value and has the potential for separation and recycling. A search revealed Chinese patent application number CN209039367U, which discloses an automatic stripping and recovery device for spent explosives rolls. This device primarily uses a clipper to remove the aluminum buckle on one side of the bag, then squeezes the bag to recover the explosives. This device primarily uses a cutting method, similar to existing manual buckle removal methods, resulting in low recovery efficiency. Therefore, there is an urgent need to develop a buckle removal device to improve buckle recovery efficiency. Summary of the Invention

[0004] Based on the technical problems existing in the background technology, the present invention proposes a buckle removal device, which realizes the automatic buckle removal of the buckle-type strip packaging bag of industrial explosive emulsion explosive, and improves the efficiency of buckle removal.

[0005] The buckle removal device proposed by the present invention comprises:

[0006] The two end covers are fixed to the machine base, and a slot with one side open is provided on the outer circumference, and the slot is used for limiting and removing the buckle of the emulsion explosive buckle type strip packaging bag;

[0007] The rotating wheel body is located between the two end covers and can rotate relative to the end covers;

[0008] The clamping assembly is arranged on the outside of the rotating wheel body. The rotating wheel body drives the clamping assembly to rotate, and it opens and closes cyclically during the reciprocating rotation process to achieve the clamping or discarding of the emulsion explosive clip-type strip packaging bag between the rotating wheel body and the clamping assembly.

[0009] Preferably, the clamping assembly includes a plurality of limit blocks arranged at both ends of the rotating wheel body and evenly distributed, the limit blocks are provided with radial sliding limit grooves, an axially distributed chuck drive shaft is installed in the radial sliding limit grooves, both ends of the chuck drive shaft are installed in cam grooves provided in the end cover, the chuck drive shaft is connected to the radial sliding limit grooves and the cam grooves in a sliding or rolling manner, and an arc-shaped movable chuck is also fixed on the chuck drive shaft, the arc-shaped movable chuck is located between the two axially distributed limit blocks, and the chuck drive shaft slides in the cam groove to achieve the sliding of the chuck drive shaft in the radial sliding limit groove so as to achieve the arc-shaped movable chuck approaching or moving away from the rotating wheel body.

[0010] Preferably, the cam groove is a closed annular groove, and the distance from the center line of the cam groove to the center axis of the end cover is not equal. When the chuck driving shaft moves to the point where the distance from the center line of the cam groove to the center axis of the end cover is the smallest, the arc-shaped movable chuck and the rotating wheel body clamp the emulsion explosive snap-on strip packaging bag. When the chuck driving shaft moves to the point where the distance from the center line of the cam groove to the center axis of the end cover is the largest, the opening between the arc-shaped movable chuck and the rotating wheel body is the largest, thereby realizing the discharge / discarding of the emulsion explosive snap-on strip packaging bag.

[0011] Preferably, the cam groove includes a first non-arc groove, a first arc groove, a second non-arc groove and a second arc groove arranged in sequence, the center line of the first arc groove and the center axis of the end cover are the same distance, the center line of the first non-arc groove and the center axis of the end cover transition from the first arc groove to the second arc groove direction, the center line of the second arc groove and the center axis of the end cover are the same distance, the center line of the second non-arc groove and the center axis of the end cover transition from the first arc groove to the second arc groove direction.

[0012] Preferably, a first mounting hole is opened in the middle of the rotating wheel body, and a second mounting hole matching the first mounting hole is opened in the middle of the end cover.

[0014] Beneficial technical effects of the present invention:

[0015] The present invention controls the rotation of the rotating wheel body through a driving device, and the rotating wheel body drives the installation shaft to move along the cam groove. Since the distances from the center line of the cam groove to the central axis of the end cover are not uniform, when the chuck driving shaft moves to the point where the distance from the center line of the cam groove to the central axis of the end cover is the smallest, the arc-shaped movable chuck and the rotating wheel body clamp the emulsion explosive snap-on strip packaging bag, and at the place where the arc-shaped movable chuck and the rotating wheel body clamp the emulsion explosive snap-on strip packaging bag, the two ends of the emulsion explosive snap-on strip packaging bag are displaced into the slots of the end cover, and the snap-on strip packaging bag is clamped. Located on the outside of the end cover, the clips at both ends of the emulsion explosive clip-on strip packaging bag can be removed by continuing to move. The overall structure is simple and convenient, and when the chuck driving shaft moves to the point where the distance between the center line of the cam groove and the center axis of the end cover is the largest, the arc-shaped movable chuck moves away from the rotating wheel body. At this time, the emulsion explosive clip-on strip packaging bag just moves to the lower end of the device, and the emulsion explosive clip-on strip packaging bag can be discarded, realizing the automatic removal of the clips and discarding of the emulsion explosive clip-on strip packaging bag, thereby improving work efficiency.

DETAILED DESCRIPTION

[0020] The present invention will be further explained below with reference to specific embodiments.

[0021] Reference Figure 1The buckle removal device proposed in the present invention comprises: two end covers 1 fixed to the machine base, with a slot 3 with one side open on the outer circumference, the slot 3 being used for limiting and removing the buckle of the emulsion explosive buckle strip packaging bag; a rotating wheel body 8 located between the two end covers 1, which can rotate relative to the end covers 1, and drives the emulsion explosive buckle strip packaging bag to rotate along the central axis of the end covers through the rotating wheel body 8, and cyclically opens and closes during the reciprocating rotation process, so that the buckle limited on the outer side of the end cover is separated from the emulsion explosive buckle strip packaging bag, thereby achieving the purpose of recovering the buckle; a clamping assembly arranged on the outer side of the rotating wheel body 8, and driven by the rotating wheel body 8 to rotate the clamping assembly, so that the emulsion explosive buckle strip packaging bag is clamped between the rotating wheel body 8 and the clamping assembly. In addition, in order to prevent the removed buckle from splashing, a detachable protective cover (not shown in the figure) is also provided on the outer side of the two end covers (1). The protective cover solves the problem of the detached buckle flying around, and facilitates the recovery of the buckle.

[0022] Reference Figure 1 and Figure 3 Specifically, the clamping assembly includes several limit blocks 6 arranged at both ends of the rotating wheel body 8 and evenly distributed. The limit blocks 6 are provided with radial sliding limit grooves 9, and the axially distributed chuck drive shaft 4 is installed in the radial sliding limit grooves 9. The two ends of the chuck drive shaft 4 are installed in the cam grooves 7 opened in the end cover 1. The chuck drive shaft 4 is connected to the radial sliding limit grooves 9 and the cam grooves 7 for sliding or rolling. Specifically, the chuck drive shaft 4 can be displaced circumferentially along the cam grooves 7. At the same time, the chuck drive shaft 4 can also be displaced radially along the radial sliding limit grooves 9. An arc-shaped movable chuck 5 is also fixed on the chuck drive shaft 4. The arc-shaped movable chuck 5 is located between the two axially distributed limit blocks 6, and the radial sliding of the chuck drive shaft 4 is achieved by sliding the chuck drive shaft 4 in the cam grooves 7. The arc-shaped movable clamp 5 and the rotating wheel body 8 slide in the limiting groove 9 to achieve the mutual approach or distance between the arc-shaped movable clamp 5 and the rotating wheel body 8. When the distance between the arc-shaped movable clamp 5 and the rotating wheel body 8 is the largest (the arc-shaped movable clamp 5 is at the top position), the emulsion explosive snap-on strip packaging bag is placed between the arc-shaped movable clamp 5 and the rotating wheel body 8. The rotating wheel body 8 continues to rotate, and the arc-shaped movable clamp 5 begins to approach the rotating wheel body 8 and clamp the emulsion explosive snap-on strip packaging bag. During the rotation, the clips at both ends of the emulsion explosive snap-on strip packaging bag are limited by the clip grooves on the outside of the end cover, thereby realizing the removal of the clips. When the arc-shaped movable clamp 5 rotates to the bottom position, the arc-shaped movable clamp 5 moves in the direction away from the rotating wheel body 8 until the distance between the two is the largest. At this time, the emulsion explosive snap-on strip packaging bag is detached from the device.

[0023] The cam groove 7 is designed as a closed annular groove, so that the chuck drive shaft 4 can slide in an annular manner along the cam groove 7 to realize the clamping and loosening of the arc-shaped movable chuck 5 and the rotating wheel body 8; and the distance from the center line of the cam groove 7 to the center axis of the end cover 1 is not uniform. When the chuck drive shaft moves to the point where the distance from the center line of the cam groove 7 to the center axis of the end cover 1 is the smallest, the arc-shaped movable chuck 5 and the rotating wheel body 8 clamp the bag body of the emulsion explosive clip-on strip packaging bag. When the chuck drive shaft moves to the point where the distance from the center line of the cam groove 7 to the center axis of the end cover 1 is the largest, the arc-shaped movable chuck 5 and the rotating wheel body 8 is the largest. If the arc-shaped movable clamp 5 is located at the top, the emulsion explosive snap-fit ​​strip packaging bag is placed between the arc-shaped movable clamp 5 and the rotating wheel body 8, and the rotating wheel body 8 is continued to be rotated so that the arc-shaped movable clamp 5 and the rotating wheel body 8 clamp the bag body of the emulsion explosive snap-fit ​​strip packaging bag and the buckle is removed. If the arc-shaped movable clamp 5 is located at the bottom, since the opening between the arc-shaped movable clamp 5 and the rotating wheel body 8 is the largest, the emulsion explosive snap-fit ​​strip packaging bag after the buckle between the arc-shaped movable clamp 5 and the rotating wheel body 8 is removed is detached from the device.

[0024] Reference Figure 2 Specifically, the cam groove 7 includes a first non-circular arc groove 12, a first circular arc groove 13, a second non-circular arc groove 14 and a second circular arc groove 15 arranged in sequence. The center line of the first circular arc groove 13 is at the same distance from the center line of the end cover 1, and the distance from the center line of the first non-circular arc groove 12 to the center axis of the end cover 1 transitions from the first circular arc groove 13 to the second circular arc groove 15 direction (clockwise). The center line of the second circular arc groove 15 is at the same distance from the center line of the end cover 1, and the distance from the center line of the second non-circular arc groove 14 to the center axis of the end cover 1 transitions from the first circular arc groove 13 to the second circular arc groove 15 direction (counterclockwise).

[0025] Reference Figure 1-3 A first mounting hole 10 is defined in the center of the rotating wheel 8, and a second mounting hole 11 is defined in the center of the end cap 1, matching the first mounting hole 10. The first and second mounting holes 10 and 11 are coaxial. A mounting shaft 2 is inserted into the first and second mounting holes 10 and 11, connecting the rotating wheel 8 and the end cap 1. The mounting shaft 2 is fixedly connected to the rotating wheel 8, forming a rotational pair with the end cap 1. One side of the mounting shaft 2 is connected to a drive device, such as a motor, via a coupling (not shown). The drive device controls the rotation of the mounting shaft, thereby driving the rotation of the rotating wheel, thereby achieving the clamping, de-snapping, and discarding of the emulsion explosive snap-on strip packaging bags. The entire device also includes a support frame (not shown). The specific structure of the support frame can be based on existing technologies, such as connecting the support frame to the end cap to achieve device installation. The drive device can also be mounted on the support frame.

[0026] Working principle: when the chuck driving shaft moves to the point where the distance from the center line of the cam groove to the center axis of the end cover is the smallest (the first arc groove), the arc-shaped movable chuck and the rotating wheel body clamp the emulsion explosive snap-on strip packaging bag, and at the place where the arc-shaped movable chuck and the rotating wheel body clamp the emulsion explosive snap-on strip packaging bag, the two ends of the emulsion explosive snap-on strip packaging bag are displaced into the slot of the end cover, and the buckles are located on the outside of the end cover. Continuing to move can achieve the removal of the buckles at both ends of the emulsion explosive snap-on strip packaging bag. The overall structure is simple and convenient, and when the chuck driving shaft moves to the point where the distance from the center line of the cam groove to the center axis of the end cover is the largest (the second arc groove), the arc-shaped movable chuck is displaced in the direction away from the rotating wheel body. At this time, the emulsion explosive snap-on strip packaging bag just moves to the lower end of the device, and the emulsion explosive snap-on strip packaging bag can be discarded. The device realizes the automatic removal and discarding of the emulsion explosive snap-on strip packaging bag, thereby improving work efficiency.
